BRAKE-SHOE PASTEiilhK.`

' Application filed January 1 To @ZZ whom, t may concern.-

Be ,it known that I, SAMUEL WEBB, a citizen of the United States ofAmerica,.residinor whic in a plied position videj a fasteningat.Glassport,`in the county of Allegheny and State of Pennsylvania, haveinvented new Brake Shoe Fastenings, of which the following isaspeciiication. This invention relates to im rovements in means forsecuring detachab e brake-shoes to brake-heads, the object of theinvention bein to provide a simple form of fastening wi firmly andsecurely hold the s'hoe andyet will permit of its rea y .removal whenworn and the substitution of a new shoe. Another object of the inventionis to proadapted for use in conjunction with brake-heads and shoes ofthe type old brakehead and app y a new one it is in common use and bywhich a shoe effectually secured to a vworn brakelhead, thus obvia-tingthe necessity of discarding a complete brake-beam and equipment wheneverthe brake-head is worn, so that a shoe cannot be applied thereto throughthe medium of the fastening means now in common use.

ln the accompanying drawings, Figure 1 is a longitudinal section-0f abrakeeshoe and head connected by my improved fastening. Fig. 2 is asimilar view showing a modification of the fastening. Fig. 3 'is adetail view of the keyA and clip removed.

Referring to the drawings, the numeral i designates a brake-shoe ofordinary cbnstruction provided with channeled upper and lower ends 2 and3 and having terminal notches 4 and `5, and 6 designates a brakeshoe ofordinary construction provided with end projections 7 and anintermediate apertured thereof.

In the ordinary construction now in common use the brake-head isprovided with apertured lugs to fit above and below the lug upon theshoe, and a -key passes through these lugs and bears upon theprojections 7 to hold the parts connected. The lugsupon the head are freuently damaged or worn away, and when tqhis. occurs the brake-beam andits entire carded, as it is found in practice that in view of the amountof labor re uired to remove an .nearly as cheap to remove the beamcarrying Specification of Letters Patent.

I beamiwith applied parts therefor, since the y discarded beam is meltedand utilized as to provide a construction of fastening which wil even inthe event of the heads being completely worn away or broken off andwhich willaccordingly permit of a new shoe beingconveniently and quicklyfas'- tened upon the damaged heads by atraiiitools, thus avoiding theexpense of high-class labor and the necessity asnow experienced odiscarding brake-beams having -worn heads. To this end I provide a key9, ongitudinally curved in the customary manner and ed to be passedthrough the apertured lug S. This key is provided with a hooked upperend 10, adapted to lie in the recess 4 and to engage the upper edge ofthe body portion of the brake-head, the lower end of the key beingadapted to rest upon the projection 7 at the lower end of the shoe. Uponthe lower end of the key is arranged a clip 11, apertured for slidingengagement with the key and provided with a lug o'r finger 12. After theapplied key has been' engaged by its hooked end l() with the upper endof 'the brake-head the clip is applied to the lower end of the key andscrap. The main object of my invention rs- 'obviate the necessity ofremoving a beam lugs upon the brakef -hand or other person unskilledinthe use ofadaptadjusted to seat within the recess 5 and-t0 bring thelug i2 to bear against the rear surthreaded opening screw 13 to bearupon the vkey and fix the permit the brake-slice beingfapplied to andremoved from a brake-head by an unskilled mechanic and in a short timewithout the use of tools and that it is not necessary in my improvedfastening to employ lugs upon the brake-head. Hence a new shoe may' befirmly and securely fastened upon a brakehead on which the lugs havebeen worn to such an extent as to be unfit for further use or from whichthe lugs have been entirolybroken away.
